Hi,
You could always just connect via USB I guess?
I'm afraid I'm not sure about logic level converters though. You could probably get away with connecting Edison's TX to Espruino's RX and using a potential divider for the voltage going the other way. There is a 40k pull-up to 3.3v inside Espruino's RX, but I doubt that would cause edison any problems (and it could be turned off in software).
